broken by single line docstrings

[samuelcolvin]

pytest-examples gets very messed up by single line docstrings, and starts finding the python code between docstrings, not the docstrings.

This results in examples being missed.

[samuelcolvin]

For example this code means pytest-examples doesn't find examples later in the file:

def _getattr_no_parents(obj: Any, attribute: str) -> Any:
    """Returns the attribute value without attempting to look up attributes from parent types."""
    if hasattr(obj, '__dict__'):
        try:
            return obj.__dict__[attribute]
        except KeyError:
            pass
